Kinetics: Units of rxn rate

[Christoph]

​Dear forum,

​as I calculate anorthite dissolution using a custom rate law in Xt1 I wonder about the reference of the kilograms in the unit of the reaction rate (rxn rate) in the text output file of GWB, which is mol/kg sec. So my question is if the kilograms refer to one kilogram of water?

Thanks for your help and kind regards,

Christoph​

Hi Cristoph,

 

Yes, it refers to the mass of the mineral dissolved per kilogram of solvent water.
